Quoting Petr Vandrovec (vandrove@vc.cvut.cz):

Strange, I'll have to look at 2.4.20-pre10-ac2 then. I do not
remember sending anything special for 2.4.20 to Alan...

Pre10-ac2 has a matroxfb_base.c with Version: 1.64 2002/06/10. Simple
pre10 has Version: 1.62 2001/11/29.

quoted

matroxfb_crtc2: secondary head failed to register
matroxfb_crtc2: CRTC2 framebuffer failed to register

It can only happen if there is not enough memory (uh...) or if
register_framebuffer() fails. And only way I can imagine is
that you run out of possible framebuffers... Can you
verify that /usr/src/linux/include/linux/fb.h contains
'#define FB_MAX 32' and not some small value like '2' ?

Both versions have 32. 

If you could print return value from register_framebuffer in 
matroxfb_dh_regit in matroxfb_crtc2.c, maybe it could reveal
problem. Maybe that using non-ac kernel fixes problem too.

I will add a printk & will let you know.
